Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | High risk | Not randomized |
Allocation concealment (selection bias) | High risk | Not randomized |
Baseline outcome measurement similar | Low risk | Similar data collected before and after intervention |
Baseline characteristics similar | High risk | Social and demographic characteristics of North and South sites differ from Sacramento at large |
Blinding of outcome assessment (detection bias) All outcomes | Low risk | Police incidence reports and data from emergency service events |
Incomplete outcome data (attrition bias) All outcomes | Low risk | Used public surveillance data |
Blinding of participants and personnel (performance bias) All outcomes | High risk | Not blinded |
Protection against contamination | High risk | Sites followed same municipal services and policies |
Selective reporting (reporting bias) | Low risk | Relevant outcomes reported |
